This invention relates generally to spray ing devices particularly intended to meet the requirements of the small orchardist, gardener'and fruit grower. Features of the invention' are the mounting of the supply tank so that it can be moved about, in wheelbarrow manner; the swinging arrangement of the tank whereby it is self-leveling and whereby it forms a foot for the wheeled frame upon which it is mounted; the mounting of a pump within the tank andflexible connection between the pump and the spraying tank also carried by the frame which mounts the supply tank; and the details of construction of the mounting and manner of assembly which permits of the swinging motion of the tank.

This application is divisional of my copending application Ser. No. 694,019, filed April 28, 1928, for Sprayers.

Q Objects, advantages and features of the inventionwill appear in the description of the drawings forming a part of this application, and in said drawings,

Fig. 1 is a side elevationillustrating the complete device;

Fig. 2 is a plan view; and

Fig. 3 is a detail section on the line 8-8 of Fig. 1. 7

Located upon the handle bars between the tank and wheel, adjacent the wheel, and upon downwardly slanting portions 10 of bars 10, is a closed pressure tank 17. This downwardly slanting arrangement of the bars, permits lowering of the center of gravity of 5 the tank 17 to stabilized equilibrium of the vehicle, and is a feature of the invention.

The means for securing the tank includes saddle straps of which there are two, each comprising sections 18 and 19. Each section 0 has an extension as a foot, which is riveted or otherwise secured to the corresponding bar 10 as shown at 21. Bolts 20 and nuts therefor clampingly secure the sections, it being understood that the sections are connected together at another point. However,

the straps may be formed from a single length of material. Brace strips 22 connect the clampingelements or straps withthe journal bolt 13, the strips being disposed one on each side of the wheel 1% as best shown in Figure 2. The frame of the wheelbarrow structure comprises a pair of forwardly converging handle bars 10 (preferably metal tubes), spaced apart but rigidly connected by transverse metal tie-straps 11 and 12, and provided at their front ends with a transverse axial bolt 13 on which the wheel 14 is journaled. This bolt connects the handle bars, so that they can be moved toward and away from one another. V

The spraying liquid, in considerable quantlty, 15 to 20 gallons, is carried in an" open tank 15. This tank is of cylindrical configuration and is arranged in upright position and has an open top. The tank is provided at its vertical sides with diametrically aligned outstanding trunnions 1G whichfit perforations on the inner sides of the handle bars 10. These trunnions are located far above the center of gravity of the tank 15 so that the tank will swing with a pendulum-like action to always assume a vertical or upright position. When the handle bars are lowered the bottom of the tank will rest upon the ground, and when these bars are lifted preparatory 75 to the act of'wheeling, the tank will always assume an upright position. A. self-leveling tank is therefore provided. The tank is mounted at a point between the straps 11 and 12. These straps act to brace the frame to prevent separation of the trunnions from the openings in the bars 10. It will be noted that in assembling, the bars 10 are first at tached by the bolt 13 and are then spread sulficiently to allow introduction of the trunnions, after which they are brought together, the trunnions entering the openings of the bars during this movement. The bars are then secured in operative relation by the straps 11 and 12. This is a feature of the invention.

Located within the supply tank 15 is a self-contained structure which includes a pump, a pressure equalizing chamber, an agitator and certain other devices, which are not claimed herein, and are therefore not more fully illustrated. The pump includes an equalizing tube 25 which tube is connected in upright position to the tank by any suitable means.

Another feature of this invention is the flexible tubular connection between the extension and the tank 17 which establishes communication between the pump and tank so that a pressure can be maintained in the tank, and which allows swinging motions of the tank 15. The connection is indicated by the numeral and may consist of a section of rubber hose or equivalent element detachably connected as at 31 at one end to communicate with the pressure portion of the pump 25, and likewise detachably secured as at 32 with a tube 34 which communicates with the interior of the pressure tank 17. It has been considered unnecessary to show what relation the element 34 has to the interior of the tank, inasmuch the present invention relates only to the arrangement of the tank 15, pump 25, tank 17, and

the flexible tubular connection 30, along with the detail of construction of frame, and the manner of mounting and assembling the tank to provide for its swinging motion and selfleveling adjustment. lVhen the pump handle 36 is operated in one direction, the rod 37 is operated to cause liquid to be drawn from the tank 15 through a suitable check valve 35, and upon handle movement in the opposite direction, the liquid is forced through the flexible connection 80 into the tank 17. The wall of the tank 15 has been broken away to show the general relation of the bottom part of the pump structure to the bottom of the tank 15.

I claim as my invention:

1. In a device of the class described, a frame, a supply tank arranged upon the frame and swingingly connected thereto, a pressure tank arranged upon the frame, a pump carried by the supply tank, and a delivery tube establishing communication between the pump and pressure tank, and of a length to permit oscillatory movement of the supply tank relative to the pressure tank.
